Yep this. First time I watched it I thought Dirrell edged it but watched it again and thought Froch deserved it. Fighters who try winning by being negative deserve to lose.
If you thought that was a bad performance his fight against Curtis Stevens is far worse. So bad that even Harold Lederman described it as “the worst fight he has ever seen.”
I was very inspired by Dirrell's performance at the time. From memory, I thought he landed the cleaner work and did enough to win and the general takeaway at the time was that Froch was gifted a hometown decision.
Essentially the argument that GGG beat Canelo the first time, because he was pressing the action more. Because he threw more punches, etc. Of course I totally reject this way of thinking, generally the less skilled you are and the worse defense you have, the more you press the action and come forward, the more risks you take, because you don't have the skills to be elusive or make an opponent look silly, like Dirrell did when he fought Froch. Essentially Froch was rewarded for trying harder than Dirrell, for pressing the action, but he wasn't able to impose his will on Dirrell. Andre was too slippery, too slick, and managed to catch Froch with many skillful shots. It was a fantastic fight, a wonderful clash of styles.
I remember watching at the time thinking it was very close, but Froch edged it. Agree with previous posters - I was surprised Dirrell didn't go on to achieve more in his career.
